How do I connect the Mailchimp MCP server to Claude?
A local package is listed as @cyanheads/mailchimp-mcp-server. Use the publisher's installation instructions for its complete command, arguments and authentication settings. A package name alone is not a complete Claude Desktop or Claude Code configuration.
The registry also lists these authentication or required environment fields: MAILCHIMP_API_KEY. Follow the publisher's guidance on which ones your authentication method needs, and keep secrets out of shared files.
Does the Mailchimp MCP server work with ChatGPT?
This listing includes a local package but no hosted endpoint. ChatGPT needs a compatible remote server; check the publisher's current instructions for a hosted option. The registry entry alone does not establish whether the vendor offers one.
How do I add it to Cursor?
Use the publisher's Cursor or local MCP instructions to fill in .cursor/mcp.json. Include its complete arguments and required environment fields; the package listing above is not a ready-to-run configuration.
